Op moved from abroad then from another district. It could obscure his/her path. It’s been a common problem that honors transfer or international students aren’t properly placed at the HS level because their GC doesn’t understand their background and they themselves don’t understand the new system.
Starting in Physical Science at a school where it’s the normal class is different from being placed there when the normal path is Biology.
It could be that OP was a borderline student in middle school but since s/hes taken the initiative to learn about the paths to AP and calculus on his/her own, s/he may well have been placed on the wrong track; if so now’s the time to fix it as the longer they wait, the harder it is to fix.
@anjal, can you detail your academic background? Were you a good student? If your family hadn’t moved, would you have been on a college track?
